Three dimensional RF coil structures for field profiling

Abstract

In one illustrative embodiment, a radio frequency (RF) coil is disclosed. The RF coil may include a plurality of transmission line elements, wherein at least one of the plurality of transmission line elements may have at least one dimension different than a dimension of another one of the plurality of transmission line elements. In some cases, each of the transmission line elements may include a signal line conductor and a ground plane conductor separated by a dielectric.

1. A radio frequency (RF) coil comprising:
 a plurality of transmission line elements, each of the plurality of transmission line elements including a ground plane conductor and a signal line conductor separated a distance by a dielectric, wherein the distance separating the ground plane conductor and the signal line conductor in a first transmission line element is different than the distance separating the ground plane conductor and the signal line conductor in a second transmission line element. 
 
     
     
       2. A radio frequency (RF) coil comprising:
 a plurality of transmission line elements, each of the plurality of transmission line elements including a ground plane conductor and a signal line conductor separated by a dielectric, wherein the ground plane conductor in a first transmission line element has one or more sidewalls disposed a first distance about a side edge of the dielectric and the ground plane conductor of a second transmission line element has one or more sidewalls disposed a second distance about a side edge of the dielectric, wherein the second distance is different than the first distance. 
 
     
     
       3. The RF coil of  claim 2  wherein the second distance is zero inches.
